Toho University Omori Medical Center

Our hospital, the nearest university hospital to Haneda Airport, was founded as an affiliated hospital of the Imperial Women's Medical College in 1925. Our philosophy is to "foster superior medical staff and promote research and development of advanced medical care, and provide warm-hearted, safe, and high quality community medical care to patients". In 2019, the International Medical Care Support Department was established to provide medical services to overseas patients in a reassuring setting.
